CALENDAR.

SPECIFICATION forming part of Letters Patent No. 337.478, dated March 9,1886.

Application filed November 2, 1885 Serial No. 181,552. (No model.)

described and claimed.

In the drawings forming a part of this specification, Figure 1 shows thecalendar device complete as it appears ready for use. Figs.2

Aand 3 are plans of the charts used in the calendar and containingsubdivisions of days and years, and Fig. 4 is an edge view of Fig. 1with charts removed.

Referring to the letters vof reference marked on the drawings, B is acase designed for hanging on the wall in the ordinary manner of usingcalendars. The face of this case bears characters subdividing the yearinto the number of each day in each month. At the top is an opening inthe form of an inverted letter T, (shown at P.) and at a in the month ofFebruary is another opening, the uses of which openings are belowdescribed.

In Fig. 2, D is a chart bearing characters representing years in anincreasing ratio, commencing with 1885, and other charactersrepresenting thedays of the week. These characiers (shown on the upperhalf of the chart) may be continued toward the right end of the chartindefinitely, according to the length of the chart. That the chart maynot be unduly long, Ihave shown such a continuation on the lower half.To use this continuation, of course the card would be inverted andoperated in the manner of operating it prior to invertion, as follows:

The chart D is inserted in the upper recess, R, of the case B, andadjusted so that the desired year is presented at the vertical part ofthe opening P. In the horizontal part of this opening charactersrepresenting fourteen days are presented, which are so arranged inrelation to the year, the dates of the months, and the construction ofthe case that the actual day the year came in on will be represented bya proper character over the vertical column, 1n which figure l appearsin January, and

the other days will be over the proper columns of the dates of theseveral months. To illustrate, take the year 1885, which is presented inFig. 1 at the year-opening. IVe iind that this year came in on Thursday,because we find THJ over the column containing l in Jan In like mannerthe other dates and days for the whole year may be traced. Toillustrate, take the 22d of October, pointed out by the pointer c. I/Vefind this is Thursday of the week in the year 1885-thus: Thursday,October 22, 1885.77

The dates in a recedingratio for the year and their days are as readilyfound as those of time not yet transpired. By sliding the chart D towardthe left, presenting 1886 at the year-opening, we find that the 1st dayof January, 1886, would come on Friday, the

days in the days-opening having been moved one column. Thus the days asnow adjusted and the dates of the months are in proper relation for theyear 1886, as they would be for any and all years to come and for anyand all past years which were presented at the year-opening of the case.The exception to this which is caused by leap-years is provided for bymarking "29 on the chart D at the proper position to be presented at theopeninga when a given leap-year is presented at the year-opening.Toillustrate, if the year 1888 be presented at the year-opening, thelower left-hand 29 on the chart will be presented at the opening a, whenthe calendar would indicate that the 29th day of February, 1888, comeson Vednesday, as IVE would thenbe over the column in which 29th ofFebruary appears. The calendar is right then for January and February.The year 1888 is repeated on the chart for the last ten months of theyear, and to iind dates for said ten months the chart is moved,presenting 1888, last l0 month, at the year-opening. This brings TIL77over the first column of month-dates,in which l in March appears. AsFebruary 29 comes on W'ednesday, of course March 1 would be on Thursday;hence it is necessary that TH. be over the column in which March 1appears. A like arrangement for leap-years is repeated on the chartevery four years.

The letters A B C, &c., in the months on the case B are for conveniencein knowing which day of the week a certain date is on.

IOO

To illustrate, over the column in which October 22 appears we rind L.Looking for L at the top of the calendar, We find Thursday is indicated.Thus October 22 comes on Thursday. This plan will be found more usefulfor other years, for the reason that in the arrangement for 1885 Sundayis in the first column ofthe month, Mondayin the second, and so on,withSatnrdayin the last; bnttakelSSG, Friday would then be in the fifthcolumn, and hence the letter L over October 22 would indicate Friday for1886.

In Fig. 3 a chart, D', is shown, of like arrangement tothe chart D,except the years are placed in a decreasing ratio, for the purpose ot'finding days and dates of' past years. rl`his chart is used by takingthe chart D out of its recess and inserting the former in lieu thereof.

For convenience in holding the chart not in use, it is inserted intheloxverreeess, It, of the case.

To nd prier dates, suppose 1858 be presented at the year-opening of thecase, We Would find that January l eame on Friday of that year, becauseFRJ would be over the column in which l of January appears.

The pointer c is so fnlerumed tothe case at r that it may be swunglaterally and adjusted vertically, so as to set the point at any date toreadily catch the eye. Thusit can beset every night to point out thenext day.

l have termed the part B a ease, because it has a front and rearinclosure,with recesses between 'l'orcontaining the Charts; but, so faras the invention is concerned. the front ealen dar-Card may have thechart otherwise movably connected with it, and this card may be a plateot' suitable material.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A calendar consisting or" a card or plate bearing associations ofcolumns of dates representi ng months of' the year. and having openingsthrough the plate, one for the year, one for the days, and one in themonth of February i'or the date 29, anda chart movable back of saidopenings and bearing Characters in duplieate (representing a leapyear)for the first two months and the last ten months, the iignres 29, andcharacters representing days, all

so arranged in relation to each other, to the openings, and to the datecolumns of the months that the proper dayswill be presented over theproper date-colnrnns for a given leap.- year presented at theyear-opening, and that 29 will be presented at the date-openingin themonth of February, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name inpresence of two witnesses.
